NetApp Disk Shelf Model Breakdown

Just came across some interesting information that I didn’t realize before, but here’s some information on why disk shelves from NetApp are named the way they are.

DS{U}{# Disks}{SAS Speed}

For example, the DS4243:
DS – Disk Shelf, 4 – 4U, 24 – the number of disks, 3 – 3Gb/s SAS interface

and the DS2246
DS – Disk Shelf, 2 – 2U, 24 – the number of disks, 6 – 6Gb/s SAS interface

and the DS4486
DS – Disk Shelf, 4 – 4U, 48 – the number of disks, 6 – 6Gb/s SAS interface
